What you will need:

  1. Phillips and straight blade screwdrivers
  2. Open end or line wrenches.
  3. A jack and a pair of jack stands or... (if required)
  4. Drive on ramps. (if required)
  5. Wheel chocks. (if required)
  6. Pliers
  7. Safety glasses.
  8. Fuel fitting tools (if required)
  9. Plugs for capping the fuel lines

Before You Start:

  • Follow these instructions carefully. Read and be sure you understand them before you begin.
  • Gather together all of your tools and supplies before you begin.
  • Allow plenty of time to do the job so you don't have to hurry.
  • Remember that these are general instructions. For more detailed instructions pertaining to your specific vehicle, consult an appropriate repair manual.
  • Safety is important whenever you're working around machinery. Beware of hot objects, sharp instruments and hazardous materials.
  • Don't substitute tools unless you're sure you won't compromise either your safety or the performance of your vehicle.
  • Never work on a vehicle that is only supported by a jack. Use jack stands to support the vehicle while you work. Work on a solid, level surface. Never jack a car up on dirt or grass.
  • Let the engine cool.

I receive a lot of questions concerning power loss, hesitation and hard starting in a vehicle. Many of these complaints can be traced to a clogged fuel filter. As the fuel filter gets older. More and more dirt collects inside it, gradually restricting the flow of fuel to the engine. A partially restricted filter will usually pass enough fuel to keep the engine running at idle or low speed, but may starve the engine for fuel at higher speeds or loads. So your engine may run fine putting around town, but sputter and lack power when you try to drive at highway speeds or pass someone.

I am often asked, "How often should I change my fuel filter?" If you have a high mileage vehicle you should replace the fuel filter once a year. By the time your car is six or seven years old, there can be a lot of dirt and rust inside your fuel tank. Normal condensation and moisture inside the fuel tank can form rust and every time you put in fuel, dirt can enter the fuel tank. All of this can cause a fuel filter to plug up fairly quickly, so replacing the fuel filter annually will prevent many problems
